interchangeably discharging the sound from the phonograph record andfrom the radio receiving set. 7

The amplifying chamber or horn of the phonograph may be utilized and theradio horn or discharge passage connected into the same, a suitablevalve being provided for connecting either said radio horn or the tonearm of the phonograph to said amplifying chamber. One of the principalobjects of the invention is to provide a convenient form of valve andoperating mechanism therefor to accomplish this purpose.

The invention will be first hereinafter described in connection with theaccompanying drawings, which constitute part of this specification, andthen more 5 ecifically defined in the claim at the en of thedescription. I

In the accompanying drawings, wherein similar reference characters areused to designate corresponding parts throughout the several viewsFigure 1 is a broken side elevation of the combined phonograph and radiomechanism constructed substantially in accordance with this invention,the valve being shown in side lines in position for using the phonographhorn or amplifying chamber for discharging the sounds from the radioreceiving set, and the position of said valve when the horn is used fordischarging the sounds from the phonograph record being indicated indotted lines, and V Figure 2 is a broken front elevation of the parts asshown in Figure 1.

.The casing of an ordinary phonograph is indicated at 1 in the drawings,and the 1 usual hinged-cover thereof is shown at 2.

A horizontal partition 3 supports the turntable 4 of the phonographwhich may be rotated by any suitable motor indicated conventionally bythe box 5. A tone arm 6- issupported on the horizontal partition 3 andcarries a sound box 7 equipped with a stylus 8 adapted to engage a diskrecord 9 mounted on the turntable 4, as usual. I

Said tone arm 6 extends downward through the horizontal partition 3 andterminates in a horn or amplifying chamber 10 preferably arrangedhorizontally in the casing 1 of the phonograph. Above said horn a branchtube 11 extends from the tone arm and carries on its free end a radioreceive'r'12. A swinging shutter or valve 13 is pivoted at 14 at thejuncture of the tube 11 and vertical portion of the tone arm 6 andadapted to place either said tone arm or said tube 11 in communicationwith the horn 10. Said valve 13 is actuated through a system of levers15 by a handle 16 pivoted at 17 on the upper face of the horizontalpartition 3 in the phonograph casing in convenient reach of the operatorwhen the cover 2 is raised.

It will be noted that toplace the radio receiver 12 in communicationwith the horn 10, so that the latter may be utilized for discharging orbroadcasting the radio entertainment from said receiver, it is onlynecessary to raise the handle 16 from the dotted line position to thesolid line position indicated in Figure 1, whereupon the valve 13 willbe swung upward to cut oif the tone arm 6 from the horn 10 and open thetube 11 extending from the radio receiver 12 to said horn. When thephonograph is to be used in the usual Way, the handle 16 is depressed tothe dotted line position shown in Figure 1, whereby the valve is moved,to shut oil the tube 11 from the radio receiver 12 and opencommunication between the tone arm 6 and thehorn 10.

v I claim:

In a phonograph, the combination with a casing and a horizontalpartition therein, of a record turntable mounted on said partition, atone arm extending through said partition and carrying a sound box toengage a record on said turntable, an amplifying'horn arranged in thephonograph casing below said horizontal partition and forming acontinuation of said tone arm, a oted handle mounted on the uppersurface radio receiver also arranged in the phonoof said horizontalpartition, and a system graph casing below said horizontal partioflevers connecting said handle with said 10 tion, a tube connecting saidradio receiver valve for actuatin the latter.
